Energy

you are right charges can never be at rest but the columbs law and electric field and other topics are being studied just imaginary, suppose that when charges are at rest they must emit a field which is called as electric field.

Concave lens. Concave lenses are thinner in the middle and thicker at the edges, causing light rays to diverge. Convex lenses are thicker in the middle and thinner at the edges, causing light rays to converge.

Burning coal produces the most carbon dioxide compared to other energy sources due to its high carbon content. When coal is burned, it releases carbon dioxide and other greenhouse gases into the atmosphere, contributing to climate change.

An inexhaustible resource is a natural resource that is virtually unlimited in supply and cannot be depleted by human use. Examples include solar energy, wind energy, and tidal energy, which can be continuously replenished by natural processes.

no it means it was an incomplete combustion causing pure Carbon (carbon monoxide or sut).

Lightning occurs when electrical charges build up in the atmosphere, creating a difference in charge between the ground and the clouds. When this difference becomes too large, it discharges as a bolt of lightning. Thunder is the sound produced by the rapid expansion and heating of air around a lightning bolt.

Above 126 K (-147 C) nitrogen is always a gas, whatever the pressure. At atmospheric pressure, nitrogen liquefies at 77 K (-196 C) and solidifies at 63 K (-210 C)

Incandescent bulbs typically convert only about 10% of the energy they consume into visible light, while the remaining 90% is emitted as heat. The heat energy produced by an incandescent globe will depend on its power consumption, with higher-wattage bulbs producing more heat energy.

No, work and energy are related but not always equal. Work is a measure of the transfer of energy from one system to another, while energy is the ability to do work. In certain situations, such as when energy is transformed into different forms, work and energy may not be equal.

yes it is but you expend energy trying to use it-planetary gravity that is-universal gravity might be more usable be we are talking zero point technology-you get what you give/cause effect/dont get nothin for free

ADP (adenosine diphosphate) has relatively lower potential energy compared to ATP (adenosine triphosphate) because it has one less phosphate group. ATP stores energy in its high-energy phosphate bonds, which can be released during cellular processes. ADP is formed when ATP releases its terminal phosphate group, resulting in the conversion of stored energy into kinetic energy for use by the cell.

The L wave, or Love wave (named after British geophysicist A. E. H. Love), causes rock to move horizontally, or side to side at right angles to the direction of the traveling wave, with no vertical displacements. L waves are surface waves that cause damage as they shake the ground underneath the foundations of buildings and other structures. This is a piece of junk.

Renewable energy sources such as solar, wind, and hydropower can be easily harnessed to produce electricity. These sources are abundant and sustainable, providing a clean and efficient way to generate power without relying on fossil fuels.

In a closed system, the total energy (kinetic + potential) remains constant, following the principle of conservation of energy. As kinetic energy increases, potential energy decreases, and vice versa. This continuous exchange between kinetic and potential energy allows the system to maintain a constant total energy.

Volcanism is mountain building resulting primarily from heat. The uplift comes because heat from inside the earth heats the overlying lithosphere, causing it to expand, lifting and swelling the surface upward. Often associated with this are volcanoes that accumulate even higher on top of the swollen earth. These processes include hot spot and subduction volcanoes. . Subduction volcanoes are generated along subduction zones at convergent plate boundaries; they are cordilleran mountains.

Second, is mechanical mountain building; that is, tension (pulling apart) and compression (squeezing together). The relief (differences in elevation) come primarily because different blocks of earth move relative to each other, either falling or rising vertically, or one block being shoved (thrust) horizontally over another.

There are not many harmful effects. There is no pollution, or greenhouse gases emitted. It is a clean, green way of producing electricity.

There have been reports that drilling down through the bedrock leads to instability in some places. The same has been reported from coal and oil mining.

Solar energy is stored in living organisms through the process of photosynthesis. During photosynthesis, plants convert sunlight into chemical energy in the form of glucose, which can be stored as starch or cellulose. Animals, including humans, then obtain this stored energy by consuming plants or plant-eating animals.

The process of photosynthesis is conveniently divided into two parts: the energy-fixing reaction (also called the light reaction) and the carbon-fixing reaction (also called the light-independent reaction, or the dark reaction).

The world uses around about 85 million barrels of crude oil each day, or 14,000,000,000,000 milliliters.

Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.

Natural gas does not contain carbon monoxide. It contains a large amount of methane. It may also contain other gases.

At one time it was frequently burned inside houses. It is now usually burned in furnaces since it may contain Radon, a radioactive gas. Radon can cause cancer.

Carbon monoxide is results in the process of making gas from coal. By using water while burning cole, the coal burns at a lower temperature producing coal gas and coke. This coke is not the stuff you drink but a form of carbon used to turn iron ore into iron. Coal gas is then burned to produce heat. The carbon monoxide turns into carbon dioxide. At one time it was used to heat homes. That was replaced by natural gas which does not contain poison.

When a road flare burns, it produces a bright flame and intense heat, often reaching temperatures around 1600°F. It also emits smoke and light to help signal for help or warn other drivers. Once the fuel source is exhausted, the flare will burn out and cool down.

nothing because there isn't any oxygen in the water and besides we wouldn't be inhaling in there anyways.............well actually bubbles form when you exhale in water but that's not the point

Lighting is electricity, and the charge follows the path of least resistance to "ground" and that would be a line sometimes zig-zaging along the before mentioned path of least resistance to the ground or other cloud with an oposing charge. that is why hills, and other raised structures are struck more frequently than flat ground, this provides the charge a quicker route to ground.

Calories from food are broken down into nutrients like glucose, which is then used as a primary energy source for cells through cellular respiration in the mitochondria. Cytosine is a nitrogenous base in DNA and RNA, not a direct source of energy for cells.
